Answer:
x=10
y=15
Step-by-step explanation:
Since we know y in terms of x, we can use substitution and say instead of-
5x-4y=-10
5x-4(2x-5)=-10
5x-8x+20=-10
-3x=-30
x=10
Substitute x into the equation-
y=2x-5
y=2(10)-5
y=20-5=15.

Answers
Answer:
x= 3/4
Step-by-step explanation:
[tex](3x - 2) = \frac{(2x-1)}{2}[/tex]
2(3x - 2) = (2x - 1)
6x - 4 = 2x -1
4x = 3
x= 3/4
Answer:
x=3/4
Step-by-step explanation:
Remove parentheses.
3x-2=\frac{2x-1}{2}3x−2=22x−1
Multiply both sides by 22.
6x-4=2x-16x−4=2x−1
Add 44 to both sides.
6x=2x-1+46x=2x−1+4
Simplify 2x-1+42x−1+4 to 2x+32x+3.
6x=2x+36x=2x+3
Subtract 2x2x from both sides.
6x-2x=36x−2x=3
Simplify 6x-2x6x−2x to 4x4x.
4x=34x=3
Divide both sides by 44.
x=\frac{3}{4}x=43
